WebToughness and High Impact Strength – Polycarbonate has high strength making it resistant to impact and fracture, and further providing safety and comfort in applications that demand high reliability and performance. The polymer has density 1.2 – 1.22 g/cm 3, maintains toughness upto 140°C and down to -20°C. Also, PCs are virtually unbreakable. The insulating capability of a material is measured as the inverse of thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability ( resistance value ). [2] In thermal engineering , other important properties of insulating materials are product density (ρ) and specific heat capacity (c) . Ver mais Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be … Ver mais Clothing and natural animal insulation in birds and mammals Gases possess poor thermal conduction properties … Ver mais Industry standards are often rules of thumb, developed over many years, that offset many conflicting goals: what people will pay for, … Ver mais • US DOE publication, Residential Insulation • US DOE publication, Energy Efficient Windows • US EPA publication on home sealing • DOE/CE 2002 Ver mais Thermal conductivity k is measured in watts-per-meter per kelvin (W·m ·K or W/m/K). This is because heat transfer, measured as Ver mais Insulation performance is influenced by many factors, the most prominent of which include: • Thermal conductivity ("k" or "λ" value) • Surface Ver mais • Thermal mass • List of thermal conductivities • Insulative paint Ver mais
